What is a series circuit?

Back

A series circuit is a type of electrical circuit where the components are connected end-to-end, so that the same current flows through all components.

Front

What happens to the brightness of light bulbs in a series circuit when more bulbs are added?

Back

The brightness of the light bulbs decreases as more bulbs are added because the total resistance increases, reducing the current.

Front

What is equivalent resistance in a series circuit?

Back

Equivalent resistance in a series circuit is the sum of the individual resistances of all components.

Front

How does current flow in a series circuit?

Back

Current flows along one pathway in a series circuit.

Front

What is the formula for calculating total resistance in a series circuit?

Back

Total Resistance (R_total) = R1 + R2 + R3 + ... + Rn, where R1, R2, R3, etc. are the resistances of individual components.

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to push the current through the circuit.

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R): V = I * R.

Front

What is the unit of resistance?

Back

The unit of resistance is the ohm (Ω).

Front

What happens to the total current in a series circuit if one component fails?

Back

If one component fails in a series circuit, the total current stops flowing because the circuit is broken.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where the components are connected across common points or junctions, allowing multiple paths for current to flow.
